Specification of Letters Patent.

Patented Sept. '7, 1915.

Application led ctober 23, 1913. Serial No. 796,881.

To all whom t may concern Be it lmown that we, vHERBERT O. CARLI?- ToN, a citizen of the United States, and res1- dent of the city of New York, borough of Brooklyn, county of Kings, and State of New York, and ERIK W. NELSON, a citizen of the United States, and resident of New Rochelle, Westchester county, and State of New York, have invented certain new and useful Improvements in Apparatus for Printing Positive Motion-Picture Films, of which the following is a specification.

'This invention relates to motion picture machines and more particularly to a machine for making the positive film from which the picture is projected.`

The object of the invention is to provide a machine of the class described which shall be simple in construction and positive in its operation and with which the pictures taken on the negative film may be reproduced' on the positive film with the greatest possible accuracy and efliciency.

In carrying out the invention we provide a machine inwhich two positive iilms may be-made simultaneously, the two sets of positive and negative films being. operated side by side from the same operating mechanism.

Certain features of construction, such as thev adjustable shutter and feeding mechanism, as well as other features of the 1nvention, will appear more fully hereinafter in connection with the description of the machine shown in the accompanying drawings as an illustration of one of the embodiments of the invention.

In the drawings like parts in the several views have been given the same reference numerals. v

Figure 1 is a sectional side elevation of the machine, taken on the line 1-1 of Fig. 2. Fig. 2 is an enlarged front elevation of Fig. 1, partly broken away. Fig. 3 is an enlarged sectional plan view on the line 3-3 of Fig. 1. (Also of Figs. 2 and 4.) Fig. 4 is an enlarged sectional side view of a portion of Fig. 2, taken on the line 4 4. Fig. 5 is a perspective view taken from a point in front of the upper left hand corner f Fig. 3 or the upper right hand corner of A frame or housing is shown at 1 in which the operating mechanism is mounted. An

electric motor 2 drives the worm 3 and its gear 4 which rotates the vertical shaft 5.. At the upper end of the verticalshaft 5 a bevel gear 6 drives a bevel gear 7 attached to the horizontal shaft 8.

The film operating mechanism is dupli cated on the two sides of the machine but for the purposes of illustration one set only of this mechanism is shown and described herein. It willbe understood that these are both driven from the shaft 8, and either set may be disconnected.

At one end of the shaft'8 a gear 9 is mounted, shown in Fig. 1, which gear meshes f with and drives a clutch gear 10, shown in Figs. 3 and 5. The gear 10 is provided on one f face with a clutch adapted to be engaged by the clutch member 11, which is operatively connected by means of the pins 12 to a collar 13 attached to the shaft 14. The gear 10 is mounted to rotate upon the shaft 14 and the clutch member 11 is slidably mounted upon this same shaft. The pins 1 2 carried by the collar 13 extend into the clutch member 11, which is moved into and out of its operative fposition by means of the yoke 15 mounted 0n the shaft 16l and turned by means of the handle 17.

A double sprocket 18 is mounted upon the shaft 14, one portion of which drives thel chain 19 and sprocket 20, (see Figs. 1 and 2), which, in turn, rotates the spur wheel 21 by means of which the positive and negative films are fed simultaneously from the rolls F and F.

The opposite side of the sprocket 18 drives a chain 22 which, in turn, drives the `sprocket 23 and spur wheel 24 for feeding the films to the lower rolls, which are rotated by means of a suitable belt and pulley arrangement from the shaft driven by the sprocket 23, shown in Figs. 1 and 2.

Referring to Fig. 3, a beveled gear 25 mounted on the shaft 14 rotates the beveled gear 26, which is provided with a long sleeve or extension 2.7 upon which a hub or collar 28 is mounted and to which one of the shutters 29 is attached and rotated thereby. A second portion of the shutter 30 is mounted upon a hub or sleeve 31 and both portions of the shutter are rotated by means of the collar 32 and the pins 33 attached thereto and which project through slots in the sleeves 31 and 2'?. (See Figs. 3, 4 and 5).

A sliding yoke 34 extends on either side of the collar 32 and the pins 35 aremounted thereupon which carry rollers 36 in an annular recess in the collar 32, by means of which the collar 32 is moved longitudinally upon the sleeve 31. (See Figs. 4 and 5.)

A gear 36 mounted on the shaft 37 is operated by the handle lever 38, which is provided with a suitable locating attachment operating in notches in the segment 39. -The gear 3G engages with a rack on an extension 34 from theyoke 34, by means of which the yoke is moved longitudinally. The longitudinal movement ofthe yoke34 moves fthe collar 32 carrying the pins33 which. project into ,the yslotsiin theflsleeves 27 land 31. (See,Eigsf,3' and4), ,These slots extend y, at different angles ,1. curving around the axis of tlie,vsleeve`sas show/nin ,F ig. 4, and the longitudinal movement of the pins33 in these slots.rotates,itliesleeves 27 31 carryingthesliutters y2%),aiid 3() in opposite directions, thus, regulating lthe amount of opening and time of exposureto the light.

An ladjustable l,screw -53 is engaged by a` .pin 54 carried by a cam framej55 which, in

turn, is operated by the cam 56 mounted on and rotated bythe shaft 14. This cam is positioned so that the cam frame 55 and pin 54 are moved outwardly at the time the lms are moved from one picture to the next. This outward movement swings the frame outwardly and releases the pressure of the glass 45 against the lms and thus allows the same to be readily di'awn forward.

A pair of lingers 57 are mounted upon an extension of the cam frame and are positioned to engage the series or' openings in either side of thel films and, as the cam 56 is rotated, the outward movement of the frame causesthese fingers 57 to engage theilms and, the `further movement ofthe cam 56 causes adownward movement of. the

cam. frame 55 and the fingers 57 `which advances the films for the next picture. i The Ascopeof the appended. claim, we .intend that all matter lcontained inthe above description or shown in the accompanying ldrawings shall bey .interpreted as illustrative merely of .I 'an f operative embodiment: fofi our. ,-ini'fention and not ima .liniiting-.sense.j,y r w i ....Wliatfweiclaim isge; .n.:af i.; i lvleans for makinggy positive l motion a piey ture, iilmsincludingfincombinatifin a. source of power, a vertical-'drivefshaftoperated thereby, a horizontahshaft` being {ope'iativelyl connected with,saidf)verticali.drive shaft,\ a' double. sprocket: on;k saidl horiontal,fshaft,
